Alright, problem half solved in certain way. At least for me. I checked again in the Scripts site and there are now two of those Display (DP) "Stealers" (don't actually steal but takes the image frome caché). The good news for me is that with the "Send message offline" new feautre, now I can open a chat window -that displays the contact's image- even if I'm as "offline" or the contact's is offline, which is way better from what I was expecting. And then there I can "steal" the Display picture.
What I don't like is that it only updates your MyDisplay value to the path of the other contact's display, and it only shows the image, 'cause what I really want is to save the image in my HD.
I was developing the script but now I just need to takes the code for saving from someone else and put it in mine, If I succed I'll make it available.
Cheers
This is an awesome board.
